LAMP WRAPPER.

Application filed March 10, 1924. Serial No. 697,988.

electric incandescent lamps against breakage.

The object of the invention is to provide an improved wrapper which will efiiciently hold the lamp.

Another object of the invention is to provide an improved wrapper for a lamp in which a corrugated strip is used around the bulb-portion of greatest diameter and the remainder is formed of fiat stock.

A further object of the invention is to provide an improved wrapper for lamps and the like which is simple in construction, can be produced at a low cost and will efficiently protect the article from breakage.

The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings: Fig. 1 is a plan of the blank from which the wrapper is formed. Fig. 2 is a vertical section of the completed, folded wrapper. Fig. 3 is a perspective of the wrapper, parts being broken away for illustrative purposes. .Fig. 4 is a plan of a portion of a blank embodying a modification showing the corrugated portions of the wrapper attached to the sheet forming the blank, instead of having integral corrugations. Fig. 5 is a detail perspective of a portion of the blank shown in Fi 4.

The invention is exemp lified in a wrapper for an electric lamp which is cut from a sheet 7 of suitable stout paper such as cardboard. The sheets for the blanks may be cut from a continuous web. Each blank is preferably made of a single sheet of stock which, when cut, creased and folded will form sides 8 and a flap 9 which is adapted to lap the outer side and to be secured thereto by an adhesive to hold the sides so they will form a four-sided box-like structure. The sides are creased on lines 11 for convenience in folding them into box-like shape. Flaps or extensions 12, integral with the blank, extend outwardly from one end of sides 8. Greases 13 are provided to facilitate the infolding of these flaps. The outer portions of these flaps are corrugated' transversely of the box, as at 10, and each of them is adapted to be folded inwardly into the position shown in Fig. 2 to form a cushion or liner ada ted to engage, fit snugly around and hol the lamp at its greatest diameter. The

flaps are folded to lie against the integral faces of the sides 8 respectively so that they will stiffen the sides. In forming the wrappers, the blanks may be corrugated continuously across the margin of the sheet where the flaps 12 are fitted and then notched or cut, as at 14, to form the flaps so they may be separately folded inwardly into operative position.

The opposite ends of sides 8 are each provided with an outer integral extension or flap 15, the outer margin of which has a semicircular notch 16. These extensions are also foldable inwardly to form means to hold the base of the incandescent lamp centrally in the wrapper and against longitudinal movement therein. The blank is creased, as at 17 to facilitate the infolding thereof and also at 18 to facilitate the transverse folding thereof. As a result of creasing the flaps or extensions 15 at 17 and 18 they can be folded inwardly so that end portions 20 between said creases may be folded to lie against the inner faces of the sides 8 respectively, and the outer end portions 21 may be folded to extend transversely of the box. When the portions 21 are folded to extend transversely they form a closure or partition around the lamp base and by which the latter will be held against displacement in the box. The semicircular notches 16 are formed to fit snugly around the lamp so that the portions 21 will be held in operative position by the lamp base. The extensions 15 are preferably folded into operative position after the lamp has been placed in the wrapper. The portions 20 position the portions 21 so that the partition or closure will be disposed inwardly of the end of the wrapper a sufiicient distance so that the lamp base will not project beyond the wrapper.

In'the modified form of the invention shown in Figs. 4 and 5 the flaps 12 consist of integral fiat extensions of the sheet form.- ing the body of the wrapper, and separately corrugated sheets 23, the corrugations extending transversely of the flaps. In forming the blanks for this modified form of wrapper the continuously corrugated strips may be secured on the blank and the notches 14 cut conjointly through the corrugated sheets and the flap backing thereof.

The invention exemplifies an improved wrapper for incandescent lamps and thellike which is box-like in form and In which cushioning means for the lamp is provided on flaps which are integral with the body of the wrapper so that they can be produced at a comparatively low cost and in large quantities. The invention also exemplifies a wrapper for this purpose in which integral flaps are used to form an aperture closure in which the base of the lamp is held.

The'invention is not to be understood as restricted to the details set forth, since these flap at one end and folded against the inlamp-sides.
